The technique for successful surgical correction of an anomalous origin of the right coronary artery from the opposite aortic cusp with an aberrant course between the aorta and pulmonary artery is illustrated in a symptomatic 62-year-old woman. The intramural course of the right coronary artery traversed the tip of the commissure between the anterior and posterior leaflets, and its repair entailed unroofing of the intramural segment from inside the aortic intima. This technique required resuspension of the overlying commissure to maintain optimal aortic valve leaflet coaptation and prevent aortic insufficiency...

OBJECTIVE: Currently, lymphedema (LED) is typically diagnosed clinically on the basis of a patient's history and characteristic physical findings. Whereas the diagnosis of LED is sometimes confirmed by lymphoscintigraphy (LSG), the technique is limited in both its ability to identify disease and to guide therapy. Recent advancements provide opportunities for new imaging techniques not only to assist in the diagnosis of LED, based on anatomic changes, but also to assess contractile function and to guide therapeutic intervention...

Lateral ankle instability is a common entity that can result in degenerative arthritis if left untreated. Acute ligament injuries should primarily be treated nonoperatively with a course of physical therapy and functional bracing. Chronic ankle instability is defined as mechanical or functional and can be diagnosed using a combination of history, physical examination, stress radiographs, and magnetic resonance imaging. After failure of nonoperative treatment, surgical treatment with anatomic ligament repair and inferior extensor retinaculum augmentation has the best clinical outcomes...

INTRODUCTION: The value of imaging the deep branch of the ulnar nerve (DBUN) over its entire course has not been clarified. Therefore, this study aimed to evaluate the feasibility of visualizing the DBUN from its origin to the most distal point. METHODS: We performed high-resolution ultrasound (HRUS) with high-frequency probes (18-22MhZ), HRUS-guided ink-marking, and consecutive dissection in 8 fresh cadaver hands. In both hands of 10 healthy volunteers (n=20), the cross-sectional area (CSA) was measured at 2 different locations (R1+R2)...

BACKGROUND: The interest for endoscopic pulmonary anatomic resections has grown exponentially during the last decade. During thoracoscopic procedures surgeons cannot rely on digital handling and operative field is viewed on a two-dimensional video monitor, thus frequently encountering anatomical difficulties. The hypothesis is that foreknowledge of the anatomy of each patient would greatly contribute to the safety and accuracy of the operation. The aim of the study was to evaluate the effectiveness of 3dimensional multidetector computed tomography (3D-MDCT) software to identify the pulmonary artery branching pattern during the preoperative study of endoscopic lobectomies and segmentectomies...

Louis E DeFrate
Injuries to the anterior cruciate ligament (ACL) frequently lead to early-onset osteoarthritis. Despite advancement in surgical techniques, ACL reconstruction has a limited ability to prevent these degenerative changes. While previous studies have investigated knee function after ACL reconstruction, in vivo investigations of the effects of graft placement on in vivo joint function and cartilage health are limited. This review presents a series of studies that used novel imaging and 3D modeling techniques to determine the in vivo placement of the ACL graft on the femur using two different ACL reconstruction techniques...

Children with ESRD in need of RRT are commonly managed by PD due to difficulty with vascular access for HD and the relatively large extracorporeal blood volume required. Major abdominal surgery may result in injury to the peritoneum and consequent adhesion, thereby resulting in a reduction in the anatomical capacity and transport capability across the peritoneal membrane. Here, we report successful resumption of PD after LDLT in two pediatric patients. The causes of ESRD were PH1 and juvenile nephronophthisis, respectively...

INTRODUCTION AND HYPOTHESIS: The majority of patients with cystocele undergoing reconstructive surgery have combined defects of pubocervical fascia and uterosacral/cardinal ligament complex. In this regard, the simultaneous correction of both defects is rational. Furthermore, decreasing the use of synthetic materials in pelvic floor surgery is an important goal. The aim was to evaluate the objective and subjective cure rate of a hybrid technique: bilateral sacrospinous fixation using modern monofilament synthetic tape (apical sling) combined with the original technique of subfascial colporrhaphy...
